In this paper, we propose an efficient dynamic workload balancing strategy which improves the performance of high-performance computing system. The key idea of this dynamic workload balancing strategy is to minimize execution time of each job and to maximize the system throughput by effectively using system resource such as CPU, memory. Also, this strategy dynamically allocates job by considering demanded memory size of executing job and workload status of each node. If an overload node occurs due to allocated job, the proposed scheme migrates job, executing in overload nodes, to another free nodes and reduces the waiting time and execution time of job by balancing workload of each node. Through simulation, we show that the proposed dynamic workload balancing strategy based on CPU, memory improves the performance of high-performance computing system compared to previous strategies.

This study aims to examine how the use of Padlet, an online platform, affects students' English writing anxiety and English writing strategy in online college English writing classes. A total of 64 college students participated in the study and completed the survey including English writing anxiety, English writing strategy and demographic information. For the study, we divided participants into 2 groups, experimental group using Padlet for their writing tasks and control group using college e-learning during a semester. The results showed that students using Padlet used more writing strategies than the students using college e-learning platform. The use of Padlet, however, was not statistically significant on writing anxiety. English writing anxiety was differed by English level, but decreased at the end of semester regardless of English level. The results imply that Padlet is a useful online learning tool for English learners to actively use English writing strategies and even for learners with low English writing proficiency.

The computational science and engineering field, which combines basic science and computing technology, has emerged as a third scientific methodology, following theories and experiments. This study aimed to identify factors and relationships that affect the continued use of the computational science and engineering (CSE) platform for its successful operation, utilization, and diffusion. To that end, the quality factors of the platform were derived by combining the information system success model and the technology acceptance model. These factors affected user satisfaction and intention to reuse through users' perceived usefulness and perceived ease of use of the platform. An empirical analysis was conducted through a questionnaire survey of 373 users of the EDISON platform, a representative CSE platform in Korea. The results revealed that all quality factors have a positive influence on perceived usefulness and perceived ease of use. Specifically, information quality has a significant influence on perceived ease of use, and system quality has a significant influence on perceived usefulness. Perceived ease of use has a greater impact on user satisfaction than perceived usefulness, and satisfaction affects intention to reuse. The results can contribute to the development of CSE platforms and the development strategy to expand the number of users.

This study was conducted to determine a 'platform' as a mean of interactions between users in contemporary spatial design and network(web) and to verify the similarity between the platform and space of Rem Koolhaas, one of the leading contemporary architects of our time. A platform, referring to tangible or intangible structures designed for common use in a variety of ways, is activated by the networking effect of participants. Aided by the recent development of the IT industry encompassing computers and smart phones, the concept of platforms is extending to all areas of modern life, in general. In this study, the similarity between architectural space and platforms after reviewing the computer-related platforms, ecological features that refer to virtuous circulation, and various cases applied with platform thinking. Through this process, the platform feature of architectural platforms is defined as the 'open spatial system combined with control and freedom that acts more than one function and facilitates direct/indirect exchanges between users regardless of its type or size'. Establishing the criteria for spatial analysis based on this definition, analysis was conducted on interior design projects that were planned and conducted by Rem Koolhaas after 2000. As a result of this analysis, it was learned that Rem Koolhaas designs space using dual space structures where the extension and mixture of the user group, mixture of various functions defined by users, loose control that induces voluntary participation, community reinforcement, and inducement of accidental events, and opening and closing coexist. In addition, this design approach was found to be a design strategy similar to the concept of platforms that began to be developed in the IT field.
